ROBERT S. BLAIR, OF SOUTH ORANGE, NEW JERSEY, ASSIGNOR TO MEURER STEEL BARREL COMPANY, INC., A CORPORATION OF NEW YORK.

STEEL BARREL.

Application filed January 9, 1919. Serial No. 270,353.

To all whom it may concern:

Be it known that I, ROBERT S. BLAIR, a

citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented an Improvement in Steel Barrels, of which the following is a specification.

This invention relates to the construction of steel barrels and the like, and with regard to its more specific aspects, to the end or chime joint portions thereof. One of the objects of this invention is to provide a construction of the" above type which shall possess strength and security in a high degree and shall be economical in the use of metal. Another object is to produce a dura ble construction ofthe above type, which can be quickly and conveniently made. Another object is to provide a simple and practical construction of the above type not dependent upon solder or holding means and which shall nevertheless be thoroughly fire-proof. Other objects will be in part features of construction, combinations of elements and arrangement of parts which will be exemplified in the structure hereinafter described and the scope of the application of which will be indicated in the following claims. a

In the accompanying drawing in which are shown one or more of various possible embodiments of the several features of this invention,

Figure '1 is a sectional View through the end or chime joint of a steel barrel;

Figure 2 is a similar view of a modified construction.

. Similar reference characters refer to similar parts throughout both views of the drawing.

Referring now to Figure 1 of the drawing, there is shown at 10 a portion of the shell or body of the barrel, the same being formed of sheet metal of suitable thickness in any desired manner.

Within the end of this shell is tightly fitted a head 11 also formed of sheet steel provided with a flange 12 which preferably rests snugly within and against the end of the body 10. v

The parts being thus assembled, it being understood that both ends of the barrel may be of identical construction, the edges of both flange 12 and body 10 are then rolled into the interlocking double seam joint shown at 13. The parts of the respective members are readily traced in the sectional view appearing on the-drawing.

A chime ring preferabl formed of malleable steel of annular con ormation is given the cross section indicated at 14 except that the outer free edge 15. extends substantially as indicated in dotted lines. The inner flange of the ring 14 is given a curved conformation to provide a concave surface at 16 and to extend upwardly and rest against tle under surface of the barrel head as at 1 The ring or hoop provided as above is thus forced within the flange or chime of the barrel, it being understood that the seam or joint 13 may be originally formed in such manner that its inner surface lies in the plane of the line 18. With the ring in position, the joint or seam 13 is rolled or spun inwardly to fit snugly within the concave surface of the inner flange of the hoop, the latter thus extending over and interlocking with the shoulder formed at 19. The outerflange 15 is bent upwardly and inwardly so as to enter and interlock with the outer surface of the joint. This outer surface will in general be of a concave form, due to forcing the seam in the concave surface 16 of the ring or hoop.

The lower surface of the hoop is preferably so formed as to provide a bearing surface at 20 which will be substantially beneath the lower end of the joint. All shocks are thus transmitted directly upwardly to the wall of the barrel without a marked tendency to displace the parts.

The head 11 at least, including its flange, is preferably galvanized on both surfaces in order that the exposed portions of the shoulder at 2lbe protected as fully as p'os- 'sible.

It is also to be noted that the chime ring shouldfit the end of the inner joint closely as at 22. Furthermore, the outer surface of the joint where engaged by the outerflange of the ring, and the opposite surface of engagement between the inner surface of this ring and tend to drive it upwardly,and if these surfaces diverge in an upward direction, there is a tendency for it to wedge the outer flange of the ring into a loose relation with the inner joint.

It will be seen that in the use of a barrel constructed as above, the inner joint is clamped between the flanges of the chime hoop and that both of these flanges interlock to a certain extent with the respective surfaces of the joint. This is brought aboutmoreover without the outer flange extending over the outer shoulder at 21 although the inner flange extends over the inner shoulder. The flanges of the chime are of such nature as to present great strength and the inner seam is formed under such pressure that the metal surfaces are tightly united. If desired, some form of plastic cement may be employed to care for isolated leaks due to defects of material or workmanship, but no solder is requiredand accordingly the barrels are thoroughly fireproof.

In Figure 2 of the drawings is shown a different form of joint in which the body of the barrel shown at 23 is provided with a head 24 flanged. at 25 as in the construction first described. The edges of the head, flange and body are rolled into a double seam joint 26, also as first described. The heavy malleable chime hoop27, however, is provided with its inner flange adapted to substantially rest against the head as at 28 and is shaped to haveon the outer surface of its inner flan e, a number of corrugatipns 29. The outer ange 30 prior to the formation of the barrel, rests substantially as indicated in dotted lines. The chimehoop being placed in position, the double seam is rolled into interlocking relation with the corrugations 29. If desired, these corrugations may be rolled into the double seam before the parts are assembled and may be either in parallel form or may form a thread .to co-act with a similar thread formed by the corrugations 29. The mechanical features of the joint are completed b rolling the flange 30 into the position indicated in full lines and thereupon the entire barrel may be galvanized to perform the functions set forth in connection with the construction shown in Figure 1.

Although both of these arrangements possess features in common and advantages. peculiar to themselves, the construction first described forms the subject matter of the most specific claims of this application.

It will thus be seen that there is provided a barrel construction of a strong and secure nature in which the objects'of this invention are achieved and that such a construction is well adapted to meet the severe conditions of hard practical use.

As various possible embodiments might be made of the above invention and as vathereof being concave.
